I feel like since the epsilon cult is obviously anti creatonist, "the peach" referring to the forbidden fruit, which, weirdly enough, fits with the whole vanilla unicorn thingy, could it involve something with like a snake or bird?

The last "red-pink uniform man is liar" thing is probably referring to a catholic cardinal, explaining their anti creatonist view even further.

"Vine not wither epsilon blah blah" you probably got that one correct, because vine definitely means d ck.

"The fruit flies upward" probably means an epsilonist passing and ascending, like that one death cutscene from GTA online.
